A method of achieving high efficiency of energy usage includes passing current through an inductor, causing the current to be repeatedly interrupted, thereby generating a back emf in the inductor and thereafter harnessing the back emf so generated to supply energy to an energy receiving or processing device. The frequency of interruptions should be 40 Hz or more and is achievable by applying rectifying means to the current. The invention extends to apparatus for harnessing such back-emf and energy generating means comprising an inductor and current interruption means connectable to an energy receiving device. |
